The proper Guix way would actually be to unvendor those packages from
Emacs and offer them separately. We could certainly do this for quite
a number (e.g. org, cc-mode, ...), but it would be work that someone
has to do and that person better not be lazy like me and take several
months to add native-compilation ;)

I think it's important to think about this in terms of forward
compatibility. Is org-roam guaranteed to always work with "the current
version of Emacs, whatever that may happen to be"? In that case, you
could currently drop emacs-org. If it requires bleeding edge symbols
on the other hand, or may freely decide that it will need them, adding
emacs-org to the inputs is a good idea.
